No, the Andes Mountain Range is not the highest in the world. The tallest mountain globally is Mount Everest, which is part of the Himalaya range in Asia. Mount Everest reaches an elevation of 8,848.86 meters (29,031.7 feet) above sea level, making it the highest peak on Earth.
The Andes, while being the longest continental mountain range in the world, extends over 7,000 kilometers (about 4,300 miles) along the western coast of South America and has several peaks that exceed 6,000 meters (19,685 feet). The highest point in the Andes is Aconcagua, which stands at 6,961 meters (22,838 feet). While significant in height and length, it does not surpass Everest.
In summary, while the Andes are impressively tall and extend across multiple countries, they are not the highest mountain range when compared to the Himalayas.
